Our improvisational comedy troupe, www.missionimprovible.com, is moving into musical activities. Although many in the troupe have musical experience, we need a place to start.

I am looking for sheet music that can be used as a guide. Example: we will probably improvise over an R&B progression and pattern. It would be great to find sheet music that included different examples of R&B, piano, base, guitar and drum. The same is true for Irish jigs.

Any help would be greatly appreciated.
